Read the RealmEye wiki.
Other than that, the game play is very intuitive. As a new player, you should be looking out for higher tier items for the class you are playing. Store any other relatively high tier items in your vault. If you find any good UT items, try not to use them until a week or two of playing.
UT = Untiered
UT items are also untradeable, which means that currently, you can only get them via drop. These items also tend to be pretty good. Some are even better than top tier equipment.
...you can find that on the wiki. :P
In general, boss/quest monsters. There are some exceptions, which would be the case for bone daggers and sprite wands, which can drop from lower leveled minions.
Either the Realmeye wiki or even the Wikin will basically answer all your questions. Maybe later I can run you through the game and hacking it on TS(You are Arthur right?)
Added on Skype anyway.
Read the Realmeye wiki and google Bluenoser's rotmg guide before you ask any more questions
